Introduction: Sonophoresis has been assessed as a novel approach to create skin permeability and drug delivery using low frequencies of ultrasound waves in the range of 20 kHz to 3 MHz. In this study, a system including seven 40 kHz piezoelectric transducers and an insulin chamber designed by the Medical Physics Research Center has been evaluated on hyperglycemic rabbits. Materials and Methods:...

background: radiotherapy has many side effects on fertilization in young women. radiation can lead to ovarian failure in women who underwent abdomen or pelvic radiotherapy. objective: this study helps us to investigate ovarian response of nmri female mice to ovarian stimulating hormones (pmsg, hcg) after whole-body gamma irradiation. materials and methods: 45 pregnant mice were divided into two...

Non-targeted effects can induce responses in tissues that have not been exposed to ionizing radiation. Despite their relevance for risk assessment, few studies have investigated these effects in vivo. In particular, these effects have not been studied in context with thyroid exposure, which can occur e.g. during irradiation of head and neck tumors. To determine the similarity between in-field a...

intra-abdominal hernias are rare conditions usually secondary to congenital defects, with pericecal hernias accounting for a minority of them. they can be difficult to diagnose due to non-specific presentations but may lead to strangulation and thus require early management. we herein report a rare case of pericecal hernia with gangrenous appendicitis in an 88 year-old lady presenting with feat...

Embryos of Chironomus samoensis are programmed, by anterior u.v. irradiation, to form the abnormal body pattern 'double abdomen'. Most double abdomen embryos show a mirror-image duplication of abdominal segments in the absence of cephalic or thoracic segments. Such embryos can be 'rescued', i.e. restored to normal development, by microinjection of cytoplasm or RNA from unirradiated donor embryo...

pneumatic rectosigmoid rapture is usually occurred following the inappropriate fun by direct entering a high volume of the air through the pneumatic device to the anus. such an event was reported for the first time in 1904 by stone. diagnosis and treatment of such injuries are often delayed because of some social limitations and preventing the patient form explaining the event. colon sigmoid ru...

aggressive fibromatosis or desmoid tumors, histologically indicated by small bundles of spindle cells in a fibrous background, are uncommon benign tumors without metastasis. they are recurrent and aggressive and their recurrence and severity is exacerbated following surgical operation. based on previous reports, these tumors rarely present as intra-abdominal abscesses. herein, a 54-year-old wom...
